Shaping glass for acoustic performance
Glass Structures & Engineering, 2022 Long Range is an experimental acoustic surface comprising 64 hexagonal, slumped glass panes, arranged in two layers of 32 panels each. It exhibits gradients of acoustic behaviors including reflection, diffusion, absorption, and transmission, accessed via modification of the form of glass panes at a variety of scales. Moving from flat panels at one end

High-performance acoustic microscope [PDF]
Review of Scientific Instruments, 1986 A commercial scanning acoustic microscope operating in the frequency range of 50–2000 MHz is described. It has a stable scan mechanism suitable for the high-frequency end to give high-resolution images and modes to allow for material characterization at the low-frequency end. The high-frequency electronics permitting a wideband operation with a variety
